Application and my as, 19m. serial im. 209,937.

This invention relates to a coffee urn and biggin therefor which is suspended in the urn and isl constructed of textile material with a substantially flat bottom whereby the o ground coffee is distributed over a wide area and hot water is sprayed toward the bottom.y

An object of the invention is to provide a nozzle arranged above the biggin so that it will not materially interfere with the removal of the biggm and the water issuing from the mouth of the nozzle is directed downward at an angle to one side of the biggin and parallel with the otherside thereby striking the entire bottom to thoroughly intermingle with the ground coffee.

Another object of the invention is to provide a pocket having a removable resilient wire member arranged to shape the bottom and keep it tensioned centrifugally so that it will not sag and the coffee grounds will scatter about the bottom.

The invention resides more particularly in the novel combinations hereinafter described and claimed, reference being made to the accompanying drawing in which;

Fig. 1 represents a vertical section of an urn embodying this invention.

Fig. 2 is an inverted plan view of the bigo'111. D In the drawing the numeral 5 designates a boiler having a cover 6 and a hot water inlet pipe 7 leading into the upper part of the boiler as is well known. n The inlet pipe is equipped with a perforated nozzle 8 the outlet or apex of which forms a right angle as indicated in Fig. 1, whereby the liquid is sprayed downward and strikes the entire bottom of the biggin. The nozzle has a stem 9 suitable for insertion into the inlet pipe and a packing ring V10 preferably made of cork prevents leakage between the joints and holds the nozzle in the pipe.

The biggin` is made of reticulated fabric and has a cylindrical body portion 11 shaped from a single piece of fabric. The bottom 12 has an inwardly turned perimeter 14 sewed about the lower end of the cylindrical body. In order toprevent collapse of the body and to retain its shape a split annular wire member 15 is inserted in a pocket formed in the upper part of a pleat 16. The pockethas open ends 17 so that the member can be slid out of the pocket.

The lower end of the body is also provided with a pleat 18 formed on the outer side of the wall' of the body having a pocket` adapted to receive an annular resilient split wire member 19 which tends to expand centrifugally thereby stretching the bottom to keep it fiat. The pleaty also has open ends 2O to permit withdrawal of the wire member. In this arrangement the wire is covered by the fabric and .being located on the other side of the blggin it can readily be removed and it does not come into contact with the liquid. When it is desired to pack, transport or clean the bag both the wire members can be removed. I Ihe biggin is supported on a flange 21 pro- ]ecting from the inside ywall -of the turn. The nozzle being positioned above the upper end of the bag and on one side thereof permits the bag t-o be readily placed or removed from the urn. The hot water when it hits the inclined forward part of the nozzle spreads and is sprayed downward toward the bottom part of the biggin' and is thoroughly mixed with the ground coffee while the extract slowly trickles through the interstices of the fabric into the boiler. y

lVhen it is necessary to reduce or increase the quantity of water issuing from the nozzle it can be slipped from the inlet pipe and another nozzle substituted with more or less perforation depending on the quantity of extract made and the time it is required to brew.r

I claim:-

1. In a coffee urn the combination with a boiler having a biggin made of fabric with a substantially flat bottom suspended therein, a water inlet pipe located on the upper side of the boiler, and a nozzle mounted on the inlet pipe having a perforated angular outletv positioned on `one side of the biggin to spray the water downward so as to strike the entire bottom of the biggin. y

2. In a coffee urn the combination with a boiler having a biggin made of fabric with a substantially flat bottom suspended therein, a water inlet pipe located on the upper side of the boiler, and anozzle removably mountedl on the inlet pipe having a right angled perforated outlet to spray the water downward toward the bottom of the biggin.

3. A coffee biggin made of fabric comprising a body and a bottom the body having an upper pleated end for the insertion of a wire ring, and a pleat located at the lower end of the outer part of the body for receiving a ranged at the lower end of the outer part o Wire member to centrfugally stretch the botthe body with a pocket for receiving a split torre resilient Wire ring to eentrfugally tension 10 4. A coffee bggn made of fabric comprsthe bottom. 5 ing a body and a practically flat bottom the In testimony whereof I have hereunto set body having an upper pleated end for the nmy hand'. sertorl of a split Wire ring, and a pleat ar- PETER G.
